According to a new Gallup poll released Friday, a majority of Americans support the proposed Buffett Rule, which would require individuals earning $1 million or more per year to pay at least 30 percent of their income in taxes.

The survey found that 60 percent of adults support enacting such a policy, while 37 percent oppose it.

By significant margins, both independents (63 to 33 percent) and Democrats (74 to 24 percent) supported the measure, a key Obama campaign issue. Republicans opposed it, but by a smaller margin of 54 to 43 percent.

The Gallup survey was conducted April 9 to 12 among 1,016 adults and has a margin of error of plus or minus 4 percentage points.
